Ultimaker 1 and 1.75 filament

Recommended Posts

Hello experts.

Anyone of you tried to convert the Ultimaker 1 to use 1.75 filament?

I found this procedure:


It looks quite straightforward, but I'd like to ask your exeperience if someone tried to do it and if there is something specific to know.

Thanks for your help.

Imho there is a simple case that favors 3mm filament over 1.75mm:


Both 3mm (which is actually 2.85mm) and 1.75mm filaments are manufactured with +-0.05mm diameter tolerance. 1.75mm doesn't go lower than 0.05mm (I believe that is pretty much impossible anyways).


2.85mm +-0.05mm = 1.8% diameter error tolerance

1.75mm +-0.05mm = 2.9% diameter error tolerance

Note that there is also +-0.1mm tolerance filament. This would make things even worse for 1.75mm filament (5.7% diameter error tolerance vs 3.5% for 3mm).

So to me it's clear that 3mm filament should be favored over 1.75mm, because variations in filament diameter result in uneven extrusion which gets you bad prints.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
